Abstract
Perturbed Angular Correlation method has been used to study the hyperfine magnetic field in the Heusler alloy Pd2MnSb(Sn). Ion implantation of the recoil 111In nuclei following heavy ion nuclear reactions 108Pd(7Li, 4n)111In and 108Pd(6Li, 3n)111In has been used to great advantage in the present case resulting in large implantation efficiency. Only a few hours of irradiation time with moderate beam current of the order of 400–500 nA resulted in sufficient implanted 111In activity on the sample for good quality measurements. The hyperfine field was measured at 111Cd probe nuclei substituting Mn and Sb(Sn) sites as a function of temperature. The fraction of 111Cd nuclei occupying Mn atom sites was found to increases with the annealing of sample at higher temperatures.
